5 Free Online Video Compressors: Compress Video Online for Free

To resize the video file size to a smaller degree, you need to figure out the parameters that affect the video size first.

Resolution:

Higher resolution means more pixels, resulting in a larger file size. (e.g., 4K vs. 720p)

Bitrate:

The higher the bitrate, the better the quality, and meanwhile, the larger the video file.

Frame Rate:

A higher frame rate means more images are displayed per second, leading to a larger file size. (e.g., 60fps vs. 30fps)

Video Encoder:

Some advanced encoders, like HEVC, VP9, AV1, etc., are more efficient than other codecs and can offer smaller file sizes for the same video quality.

Video Duration:

Generally, with the same bitrate, resolution, and video encoder, longer videos will have larger file sizes.

Audio Settings:

Audio bitrate, sampling rate, and channels also contribute to the overall file size a little.
